Updated Borg Variant, Klingons, Romulans and Shadows

[Master Belisarius]

I kept the old colony ship design, because the AI can use the standard colony ship in the beginning of the game. But also, have included a new colony ship design, based on the Light Cruiser hull.
The idea was to create a more fast colony ship, with extended fuel range, self-destruction device, an small weapon to kill ships without weapons, and cloak capabilities (when the technology is available of course). Also, I wanted to keep the colony ship with an small size, because if not, a biggest ship _ in my view _ could take a long time to be constructed, and _ in my view again _ could be very expensive.
After research the LC, the AI stop to use the standard colony ship, and start to use the new colony ship design.
